phone running slow...everything has loading time.Support

Ive had my evo since day one. Absolutely love it. It's just that within the last month it's been taking awhile to open anything. If I click on mail it seems as though it stalls for awhile, then "loading" screen then it opens. Same thing with the messenger to check my text. Again with the loading screen which stays open longer than it use to. Ive tried to reboot here and there but it doesn't seem to make any difference. I just miss the way my phone use to run and open everything up so quickly. Im not complaining, if this is normal than o.k... I can wait a few more seconds.
Is it that I have too many apps. Ive used up most of my space on my sd card, is that it? I have my phone stock. Is it time to root and will this solve my problem?

So there was some programs like QIK running....haven't opened that one in months.
But theres a bunch more that I don't know they do and Im sure some are important. Here is the list.

1. Under the tab "Calender" is OBEXSERVICE.
2. "Google Services Framework" is GOOGLE MESSAGING SERVICE. (Obvious one here but it gives me a warning and I use messenging often so maybe I should leave this alone?)
3. "Voicemail" is CM_SERVICE...Im guessing this is o.k to leave alone?
4. "HtcDmService" is AGENTSERVICE . No idea what this is.
5. ".com.smithmicro.dm" is DMSERVICEAP....No idea what this is.
6. "Touch Input" is TOUCH INPUT... ????
